Jeremy Hunt has come under increasing pressure after last week's Leveson revelations

David Cameron and Jeremy Hunt face "huge" questions over their handling of News Corporation's BSkyB takeover in the wake of the latest evidence to the Leveson Inquiry, Labour leader Ed Miliband said on Saturday.

Ratcheting up the pressure on the Prime Minister and his beleaguered Culture Secretary, Mr Miliband said this week's disclosures provided "yet more" evidence that Mr Hunt should not have been given responsibility for the deal.

The document, sent just weeks before Hunt was given quasi-judicial oversight of the bid, expressed concerns that referring the bid to Ofcom could leave the Government "on the wrong side of media policy".

"He wrote a memo to the Prime Minister for the bid four weeks or so before taking charge of it and I think it really calls into question David Cameron's judgment about why he appointed him in the first place to take over this bid.

"Here is somebody who was an advocate within Government for the bid, so there are huge questions for David Cameron to answer.

"And there are yet more questions for Jeremy Hunt to answer. I mean, why did he tell the House of Commons that he wasn't intervening in this issue when he wasn't responsible for it when, in fact, he was?

"There are just a whole series of mounting questions and we do need answers."
